If T is a vectorizable type and is_abi_tag_v<Abi> is true, provides the member constant value equal to the width (number of elements) of simd<T, Abi>, irrespective of whether simd<T, Abi> is supported or not. For any other types T and Abi, there is no member value
If the program adds specializations for std::simd_size
or std::simd_size_v(since C++17)
